Do not take unless you want to spend 30 hours a week doing over complicated physics. The content online is completely different to what you will do in workshops, and the kind of questions in workshops is what will make up the exam that is half your grade. The lectures were made in 2014, so do not expect any current topics, and good luck asking the conveeners about it. Brian is often traveling internationally, and stops by occasionally to mention his nobel prize and then disappear. Paul is ok, but good luck getting much out of his during workshops. Answers are never given after workshops, so you never know if you were right until you get your mark around 6 months later, so any hope of learning from your mistakes is futile.
